A printing device can reduce the length of roll paper that is printed, and enables easily knowing how much the printed length of roll paper was reduced. A printer 200 has a print unit 240 that conveys roll paper in the conveyance direction H and executes a printing process of printing images on the roll paper; a reduction processor 222 that controls the print unit 240 in the printing process to reduce the length of roll paper to which images are printed in the conveyance direction; a calculator 223 that calculates how much the printed length of roll paper was reduced in the printing process; and a display unit 252 that displays information indicating the reduction in the printed length of the roll paper calculated by the calculator 223.

An image forming apparatus comprises an accommodating unit that accommodates recording materials and a feeding unit that feeds an accommodated recording material, detects a fed recording material, and measures time from a predetermined timing until a recording material is detected. An information processing apparatus receives measured time data from the image forming apparatus, classifies the received plurality of time data into a first group and a second group in accordance with a length of time, selects a group for predicting a remaining life time of the feeding unit from the classified first group and second group, and predicts a remaining life time of the feeding unit using time data included in the selected group.

An image forming apparatus includes a management application and a common application. The management application manages a counter. The common application is other than the management application. The management application causes the image forming apparatus to function as: a counter managing unit that manages the counter that counts a count of executions of specific processing by the common application; and an execution count unit that counts the count of executions using the counter managed by the counter managing unit.

The location of a printing device is determined. Environmental conditions in which the printing device operated when printing a print job are determined based on the determined location. An environmental adjustment factor for the printing device is determined based on the determined environmental conditions. A predicted print material usage of the printing device in printing the print job is adjusted based on the determined environmental adjustment factor.

A printing system includes at least one processor that acts as a storing unit and a determination unit. The storing unit causes history data about a print job to be stored into storage. The determination unit determines whether to cause a user to perform confirmation processing at a time of printing based on the history data about the print job that is stored in the storage.

The present information processing apparatus sets a transmission standby time in accordance with a user instruction, detects a link-up, transmits an SLP packet, times an elapsed time from detection of the link-up, and in accordance with the elapsed time reaching the transmission standby time, controls so as to transmit an SLP packet.

A method is disclosed. The method includes receiving print job data at a printing system, tracking resource objects in print job data while the print job data is rasterized to generate rasterized print data and updating a count of resource objects for print job data confirmed as printed.

A method of processing and storing control process parameters of a 3D printer is disclosed. The processed data are converted into a binary file located in the PC, and then the contents of a binary file is transferred to the printer data memory. The printer controller performs the execution of the program contained in the read-only memory of the printer controller by generating signals for printer actuators based on the numbers, in the integer form, downloaded from the data memory.

A printer includes a control unit and a printing unit. The control unit determines whether a portion of the print image referred to as a target region is blank. The printing unit cancels printing of the print image when the control unit determines that the target region is blank.

A policy-based printing system is implemented to allow access to a private domain to print using a public domain. The private domain includes private servers that store documents. The public domain includes servers and a printing device. A public policy server uses a domain list and a protocol connection with a private authentication server to validate a user and identify which private domain to access. The public policy server receives requests from the printing device to process a print job of a document in the private domain. The private server processes the requests using the policy and a ledger to determine whether to allow the print job to the printing device. If a parameter of the policy is exceeded, then the private server allows an overage for the parameter so that the document is accessed.
